10.4.1 Insulation against condensation
Property damage
When warm air meets cold surfaces, condensation can
result.
For outdoor air and exhaust air ducts, usevapour
proof thermally insulated pipes.
If the supply and extract air ducts are routed
through unheated rooms, insulate these ducts as
well.
10.4.2 Connecting air ducts to the appliance
You can connect air ducts with
appliance.
Air ducts with diameter DN 125
Push the air duct onto the air connection.
Secure the air duct at the appliance air duct connection with
self-adhesive aluminium sealing tape.
Optional: Air ducts with diameter DN 150
Remove the air duct connectors
condition by undoing the screws.
Screw the new air duct connectors onto the appliance.
10.4.3 External wall outlets
Install the outdoor air intake into the building at a location where
contamination (dust, soot, odours, flue gas, microorganisms, ash,
exhaust air) is as low as possible.
When installing external wall outlets, prevent any short circuit
between the air intake and the air discharge.

two different diameters to the

10.4.4 Silencers
Install a silencer in both the supply air duct and the extract
air duct. Install these silencers as close as possible to the ap-
pliance, so that noise is suppressed at an early stage.
We recommend installing additional silencers if required to avoid
sound transmission.
If a room with a high noise level needs to be ventilated, install
additional silencers upstream of this room to reducesound trans-
mission to the neighbouring rooms.
Aspects such as carried voices and impact sound must also be
taken into consideration in the case of ducts
crete. Carried voices should be avoided by designing the duct with
separate branchesto the vents. If necessary,insulate the supply air
ducts, e.g. if they are mounted outside the insulated wall panel.
10.4.5 Overflow apertures
Living rooms and bedrooms are only supplied with air. Air is only
extracted from rooms where odours and moisture are generated.
Ensure an unimpeded overflow and consequently air balancing.
Install ventilation grilles in internal doors or walls, or enlarge the
air gap beneath the door to
10.4.6 Cleaning apertures
Fit cleaning apertures when installing the air ducts, so
that the air ducts can be inspected and cleaned at regular
intervals.
10.4.7 Supply and extract air vents
Supply and extract air vents for the living space are available for
wall or ceiling mounting.
When venting the kitchen, ensure that the extract air vent is fitted
as far as possible from the cooker.
10.5 Programming unit
10.5.1 Installation location of the programming
The programming unit is connected with an PC bus. The length
of the bus cable between the programming unit and ventilation
unit must not exceed 20 m.
Observethe following installation location requirements to ensure
correct function.
Fit the programming unit to an internal wall, but not in a
recess.
Do not cover the programming
Do not expose the programming unit to any direct external
heat source (e.g. the sun, a heater or a TV set).
Avoid direct draughts coming from windows and doors.
